Be it known'xthat' I, 'Josnrn C. semen, citizen of the "United States,- residin at of New Jersey, have invented. certain new whichthe following is a specification. I

This invention relates to horn base Iconstructionsfor radio receiving sets, and be- 1 longs to that class or typeof sound amplifying contrivances comprising hollow bodies of greater or less 'length, of which the cross-- sectional area, usually circular increases 'fashioned with spirall arranged tinuously enlarging c annels forming toerected a hollow cyhn rlcal chamber -J,

gradually irom'one end to the openltrmnp'et' mouth thereof, and are termed loud, speakers. a v v 7 An object of this invention is-the production ofa tone resounder 'or intensifier of the generalcharacter stated,'having parts of special structure and disposition, includ ing a base comprising divisional portlons gether a sound passage and whereb a considerable increase of length is attained beyond that usual in such articles, and by which it isbelieved the harshness. and often unnatural ad partially discordant quality of reproduced muslc, whether vocal or-instrumental, are eliminated and the com os i ferred shape and location of the various wall of the telephone to position the same parts or'members are illustrated, and Fi 1 represents a top plan view partly bro en away to disclose the spiral channel.

This invention and conslightly raised i U teeth 7: of the rin are in engagement with 1924'. Serial in. m. I

' 'Throughoiit the drawingsanddescription V the same letter is'used to refer to the same .part. and useful Improvementsin Horn Bases, of

- I designated-by letters A'and B, which are The (ii-visited portions a the. base are held together by posts D. r

.That portion of the spiral channel formed in the upperportion B of the base is marked the screws 0 let into side E, and thexcomplemental portion of the channel in the lower part-A of the base is referred to by the letter F. The spiral" course of the channel is indicated by the brokenlines in Fig. 1, and its increased length will be noted. At'the larger end of the channel is .the upwardly turned horn connectionjG, usuall this connection the '6m H is supported. I a is not confined to a horn of any shape or size.

Upon the upper base ortion Bthere is termed for the purposes of this explanation a telephone seatin chamber, as its function is. to receive thete ephone earpiece. It will be noted that the chamber J has in it s bottom an opening 7', extending downwardly and in communication with the smallest ar;

o the chamber J is provided with a track or interrupted screw thread K, and, consider-p ing' Figs. 3, .4 and 5,it will be noted that the of the spiral channel. The inner 'wa telephone holding ring L hasonits periphery a number of spaced teeth ligand that the teethengage the track or threads K. It will be further observed with respect to the ring L, that its annular portion 1s. provided with. the inwardly extending and erpieces M. After the the iraItrack. the ring may be turned pieces M, so that the ring may be moved downwardly by rotating it, and brought. into pressure-contact with the telephoneearpiece N, shown in the chamber J -8. Thus, the function ofthe holdlng ring is to press downwardly upon the upper sur face of the earpiece N. In addition to holding the earpiecefirmly down upon the bottom ofthe chamber or u on the rubber Washer 11. which may e us it 1s deslrable that the sound opening or center of the earremovable, and in by p acing the [thumb and finger-.011 the piece shall coincide with the opening j in the bottom of the chamber, which is the bebeginning of the spiral channel conveying the sounds to the horn H. This centering or positioning of the earpiece is accom plished by the revoluble ring 0 placed on the bottom of the'chamber, and carrying a number of outwardly bowed springs P. As best shown in Fig. 6, the periphery of the ring 0 has a number of spaced recesses Q, and when the ring 0 is placed in the chamber care is taken to have the projections R, formed on the lower portion of the inner wall of the chamber, enter the recesses near corresponding ends thereof. This arrangement brings the projections B into contact with the bowed springs 1? near that end of each spring which is secured to the ring 0.

Now, it will be seen that by rotating the ring 0 clockwise, the projections R press upon the outwardly bowed parts of the springs and move their free ends inwardly into a yielding contact with the side wall of the earpiece N.

The operation of this invention will now be understood 1n view of the foregoing 'ex-- planation. The associated channeled components of the base afl'ord a long gradually enlarging sound passage which renders the sounds smooth and harmonious, while the holding ring L and the adjustable springcarrying ring 0, suitably and firmly secure the earpiece in exactly the proper position in the chamber J, into which it is perfectly convenient to place the earpiece or to remove it, and the full volume of sound from the earpiece is sent directly into the spiral sound passage in the base.

Having now described this invention and explained the mode of its operation, what I claim is 2-- 1. A horn base comprising a telephone seating chamber, said chamber having an opening leading downwardly, said base composed of upper and lower portions fitting and secured together, the said portions having formed therein a spiral and gradually enlarging channel in communication with the said opening of said chamber, and the said base aving an external horn connection terminating the said channel.
